I have an Averatec 2370 laptop with the nVidia MCP51. With kernel2.6.20 I had no issues with ACPI however with 2.6.21 and higher thekernel will hang on boot until I press the suspend button or the powerbutton in which case the kernel wakes up and finishes the bootprocess. Including the following support only causes the issue:

[*] ACPI Support

What I mean by that is every ACPI option has been deactivated and onlyACPI support checked. The boot process with 2.6.21 and higher hangs atthe point where the Scheduler is being registered.

io scheduler cfq registered (default)

If I allow it to sit there it never comes back to life and finishesbooting. If I press the power or suspend button it will finish bootingas expected.

I've scoured google for quite a while but cannot find any relevantinformation pertaining to this issue. For now I've disabled ACPIaltogether.-To unsubscribe from this list: send the line "unsubscribe linux-kernel" inthe body of a message to majordomo@vger.kernel.orgMore majordomo info at http://vger.kernel.org/majordomo-info.htmlPlease read the FAQ at http://www.tux.org/lkml/
